python/samba/tests: PY3 port samba.tests.dns

Misc hanges needed to get make test TEST=samba.tests.dns &
samb.tests.dns_fowarder to run and pass under PY3

* socket.send needs bytes not string
* rec.dwTimeStamp expects int not float (in PY3 / operator
  will give float results, for int use '//' instead)
* re.match using bytes needs a bytes search term
